Sound proof wall apparatus having assembly type integrated sound proof wall base using precast concrete fixed by pile and method for constructing the same

PURPOSE: A soundproof wall assembly with a prefabricated integrated soundproof wall base using precast concrete fixed by piles and a construction method thereof are provided to reduce construction time by using precise concrete modules produced in a plant. CONSTITUTION: A soundproof wall assembly with a prefabricated integrated soundproof wall base using precast concrete fixed by piles comprises piles(100), precast concrete(200), soundproof wall posts(300), soundproof wall panels(400), first fastening units(500), second fastening units(600), and coupling units(700). The piles are installed on an earth surface at uniform intervals. The center of the precast concrete is coupled to the piles. The soundproof wall posts and the soundproof wall panels are installed on the top of the precast concrete. The first fastening units couple the piles and the precast concrete. The second fastening units couple the precast concrete and the soundproof wall posts. The coupling units connect the precast concrete coupled to the piles.
